I few weeks ago I drove on 0 for 6 or 7 miles! Fill up was 11.88 gallons. I was pretty nervous needless to say. Was driving to San Fran, passed a gas station and it said I had 60 miles to go in my car and the next city was 45 away. Figured I'd be ok. But for me, when I hit about 36 miles to go, it drops extremely quick till about 16 - I maybe can go 10 miles and it drops 20 off the gauge which is somewhat annoying.
